then after i'm not sure how they got:
Minimum occurs at 59.16 ft for the length (found on a graphing calc)
width: 10500/59.16 = 177.5 ft
Perimeter = 710 ft

ok, well the method they got the minimum is just by using a graphing calculator with a max min function on it
doing it manually would involve finding the first derivative of the equation and then setting it equal to zero and then solving for L
